Abstract

A method and a device for wireless information transmission between a base station radiating a broadband radio-frequency signal preferably generated in accordance with the Direct Sequence Spread Spectrum (DSSS) method and a multiplicity of subscribers are described. The subscribers are located at different distances from the base station. The subscribers code the received radio-frequency signal in accordance with the code division multiple access (CDMA) method according to the information to be transmitted, modulate it and reflect it back to the base station. The base station effecting a signal correlation and demodulation, and the base station automatically compensates for different propagation losses between the subscribers located at different distances from the base station in that the correlation function, on the one hand, and the propagation loss, on the other hand, are linked to one another in an inverse relationship.
